Creating RAID-0 (Stripe) Volumes

Caution - Do not create a stripe from an existing file system or data.
Doing so destroys data. To create a stripe from existing data, you must
back up the data, create the stripe volume, and then restore the data
to the volume.

Caution - Do not create volumes larger than 1Tbyte if you expect to run
the Solaris software with a 32-bit kernel. Additionally, do not create volumes larger
than 1Tbyte if you expect to use a version of the Solaris OS
prior to the Solaris 9 4/03 release. See Overview of Multi-Terabyte Support in Solaris Volume Manager for more information about
large volume support in Solaris Volume Manager.

How to Create a RAID-0 (Stripe) Volume

Before You Begin

From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. Choose Action⇒Create Volume, then follow the instructions in the wizard. For more information, see the online help.

Specifies the name of the volume to create. For information on naming volumes, see Volume Names.

number-of-stripes

Specifies the number of stripes to create.

components-per-stripe

Specifies the number of components each stripe should have.

component-names

Specifies the names of the components that are used. If more than one component is used, separate each component with a space.

-iinterlace

Specifies the interlace width to use for the stripe. The interlace width is a value, followed by either `k' for kilobytes, `m' for megabytes, or `b' for blocks. The interlace specified cannot be less than 16 blocks, or greater than 100 megabytes. The default interlace width is 16 kilobytes.

See the following examples and the metainit(1M) man page for more information.

This example shows the stripe, d20, consists of a single stripe (the number
1). The stripe is composed of three slices (the number 3). Because no
interlace value is specified, the stripe uses the default of 16 Kbytes. The system
confirms that the volume has been set up.

Example 9-2 Creating a RAID-0 (Stripe) Volume of Two Slices With a 32–Kbyte Interlace Value

This example shows the stripe, d10, consists of a single stripe (the number
1). The stripe is composed of two slices (the number 2). The -i
option sets the interlace value to 32 Kbytes. (The interlace value cannot be
less than 8 Kbytes, nor greater than 100 Mbytes.) The system verifies that
the volume has been set up.
